空调净化装置降解室内甲醛的实验研究

Experimental Study on Reducing Indoor Formaldehyde by Using Purification Device in an Air Conditioning System

现有中央空调系统大多因缺少净化装置导致室内空气品质恶化。为此,本文介绍了一种适用于空调系统的空气净化装置,模拟室内污染空气对甲醛进行净化效果测试。结果发现,采用该装置比单独采用活性碳纤维、活性碳纤维与紫外灯结合、活性碳纤维与纳米二氧化钛组合对甲醛的净化效果分别提高27.1%,19.1%和10.5%,对室内有害气体有很好的净化作用。

Most of existing central air-conditioning systems are short of purification devices so as to deteriorate indoor air quality.This paper presents a type of purifying device in air conditioning,studies the test result to find the amount of indoor formaldehyde.Tests were conducted with activated carbon fiber individually,activated carbon fiber and ultraviolet light,activated carbon fiber,ultraviolet light and nanometer titanium dioxide respectively.The results show that formaldehyde purification rate is 74.5% in last situation,which is higher than that of three others by 27.1%,19.1% and 10.5% respectively.
